Abstract: Provided are a display device, a method of fabricating the display device, and a tiled display device including display devices. A display device includes, a substrate including a first surface, a second surface opposite the first surface, and a first side surface disposed between the first surface and the second surface, a light emitting element disposed on the first surface, a side wiring disposed on the first surface, the first side surface, and the second surface, and an overcoat layer covering the side wiring, and the overcoat layer includes at least one of CaCO3 and xCaO·ySiO2·zH2O where x, y, and z are natural numbers.
